Tip & How-To about Yamaha YPG-625 (YPG625) Digital Piano

YPG625 Humity problem

The overal sound of yamaha YPG 625 and keys operation are exellent by the price. The only problem I eperienced is the instrument operation under high humidity environment. Under this condition many keys sound loud over others, furter more with no expectation from mucisian. This problems is normal for that model because the music store change my previously YPG625 for the same problem

Sometime I solve the problem to located the instrument under sun exposure and cover the keys and display to avoid direc sun exposure.

Another is apply with a hair dryers over the keys. But is very disconform situation, and I dont know if the Yamaha exposed this isntrument under high humidity environment durig the product test. I has a Ymaha very low budged digital piano and Roland controller A33 in the same condition and never eperience problems, only with this model.

Middle D key apparently was jarred loose in transport. It is sticking up and won't return to its original position, and playing the key produces no sound.


Call Yamaha at 714-522-9000 and ask for a tech who works in your area. Attempting self repair could void any garuntee that is covering the problem.

no sound on one key


That's very annoying! The keys press on to a contact strip running the length of the keyboard. Over time this wears out and notes can either stop being dynamic or stop playing altogether. You can buy the strip off ebay and have a go replacing it yourself - not too expensive. I paid someone 50pounds to supply and fit one to a 61-note keyboard.

Rhythm accompaniment does not play. Start button flashes 3 green then 1 red. Began when someone randomly pushed number buttons on the key pad.


Do an initialization (factory reset) by holding the HIGHEST WHITE key down and turning on the power. Hold the key for an extended time until display confirms initialization complete. This will restore unit to factory defaults.
